So I dumped 10-12 wheelbarrows full of recycled stone into the keyhole. Used a dry line and mason's level to get it level. Tamped it. Next came the sand. Repeated the same process. Not too sure I used enough sand as it just covered the stone. We'll see how the pavers settle this week. I can always add more. Next came the pavers. Pretty straight forward here. Used a grinder to made cuts when needed. I need to dump and tamp sand to lock pavers in. More progress in the next week or two.
